Harpoon

A harpoon is a long spear-like instrument used in fishing, whaling, sealing, and other marine hunting to catch fish or large marine mammals such as whales. It accomplishes this task by impaling the target animal and securing it with barbs or toggling claws, allowing the fishermen to use a rope or chain attached to the butt of the projectile to catch the animal. A harpoon can also be used as a weapon.

History

In the 1990s Zaire (nowadays the Democratic Republic of the Congo), harpoon points, known as the Semliki harpoons or the Katanda harpoons, were found in the Katanda region. As the earliest known harpoons, these weapons were made and used 90,000 years ago, most likely to spear catfishes.

Later, in Europe, spearfishing with poles (harpoons) became widespread in palaeolithic times, especially during the Solutrean and Magdalenian periods. Cosquer Cave in Southern France contains cave art over 16,000 years old, including drawings of seals which appear to have been harpooned.

There are references to harpoons in ancient literature; though, in most cases, the descriptions do not go into detail. An early example from the Bible in Job 41:7: "Canst thou fill his skin with barbed irons? or his head with fish spears?"

Harpoon (series)

Harpoon is a series of realistic air and naval computer wargames based upon Larry Bond's miniatures game of the same name. Players can choose between either the Blue or Red side in simulated naval combat situation, which includes local conflicts as well as simulated Cold War confrontations between the Superpowers. Missions range from small missile boat engagements to large oceanic battles, with tens of vessels and hundreds of aircraft. The game includes large databases containing many types of real world ships, submarines, aircraft, and land defenses (i.e. air bases and ports).

Overview

The simulations have a dedicated fan base with several websites offering a varying styles of scenarios and discussion forums, especially as the latest edition includes a feature to allow players to create their own scenarios. Often described as a "niche within a niche market," development of the simulation has progressed steadily through the years despite the overwhelming numerical and graphical superiority of first-person shooter and real-time strategy games. Advanced Gaming Systems, Inc. (AGSI), developers of Harpoon 3 Advanced Naval Warfare and Harpoon Commander's Edition (with HarpGamer), currently distributes the simulation as a Harpoon Ultimate Edition through Matrix games with technical support handled on a co-operative basis by AGSI, HarpGamer, and Matrix games employees.

Tycho (musician)

HIDDEN ERROR: Usage of "date of birth" is not recognized

Tycho (pronounced like Tie-ko, with emphasis on the first syllable) is an American ambient music project led by Scott Hansen (born 1976 or 1977) as primary composer, songwriter and producer. Hailing from San Francisco, California, he is known as ISO50 for his photographic and design works. His music is a combination of downtempo vintage-style synthesizers and ambient melodies. The style of his music is very organic, typically incorporating clips of the human element into his songs (i.e. weather broadcasts, simple talking, or even breathing). His song, "Dictaphone's Lament", was used as the track on a music video entitled "Live Life to the Fullest", which was made by and featured on the action cartoon block Toonami. His song "Cascade" (originally made for an Adult Swim and Ghostly International compilation called Ghostly Swim) was played during the final moments of the original 11-year run of Toonami in 2008. As of December 2014, Tycho is signed to, and has released under, Ghostly International, but has also released music on Merck Records and Gammaphone Records.

Tycho (crater)

Tycho (/ˈtaɪkoʊ/) is a prominent lunar impact crater located in the southern lunar highlands, named after the Danish astronomer Tycho Brahe (1546–1601). To the south is the crater Street; to the east is Pictet, and to the north-northeast is Sasserides. The surface around Tycho is replete with craters of various sizes, many overlapping still older craters. Some of the smaller craters are secondary craters formed from larger chunks of ejecta from Tycho.

Age and description

Tycho is a relatively young crater, with an estimated age of 108 million years (Ma), based on analysis of samples of the crater ray recovered during the Apollo 16 mission. This age suggests that the impactor may have been a member of the Baptistina family of asteroids, but as the composition of the impactor is unknown this is currently conjecture. However, simulation studies give a 70 percent probability that the crater was created by a fragment from the same break-up that created asteroid 298 Baptistina; which was previously believed to be responsible for the formation of Chicxulub Crater and the extinction of the dinosaurs. However, that possibility was potentially ruled out by the Wide-field Infrared Survey Explorer in 2011.
